Application filed .Tune 1, 1914, Serial No.-842,198. Renewed January 15,1916. Serial No. 72,373.

' To all 'whom t may concern:

vBe it known ,that III1LBERT L. FALK,y av citizen of the United States,vresiding at Philadelphia, Pennsylvania, have invented certainImprovements in Gas-Irons, of which the following isa specication.

One-objectof my invention is to provide anovel form of gas heated ironwhich,'1n j addition .to including means whereby .the supply of gas maybe conveniently Vregulated, -shall also include means forY govern- :ing:the mixture ofv air and gasdeliveredtoVv j L Thisfis held to the enditsv burner.

`tionshall be such that thelsupplyofgas 'shallf automatically u be cutdown to an' amount sufficient to keep the iron Aproperly in order thatunderoperating conditions its heated `when it is not vin use,` thearrangement of .parts being'such that while the ironrk j is inop'erationthe supp'ly .of gas is. mainltained at a maximumfwith but little eort vonthe'part of the operator. Another object of lthe invention is tolprovide va gas iron .with novely meansforretaining or storing theheat,fromv the burner temperature will remain substantially constantregardless of the material on which it is used. v

These objects andother advantageous ends Iy attain as hereinafter vsetforth, reference being had to the accompanying drawings, in whiclniFigure1 isa-vertical longitudinal section illustrating'aniron madeaccording to myl invention, and Fig. 2 v1s a transverse sectionl v on areduced scale taken on the line a-a,

Fig. 1.

In the above drawings, 1 represents a hollow casting constituting thelbody of the iron which is of any suitable shape and size-. y dependingupon the work for which it is designed,there being a cover plate 2 heldin lplace by screws 3 closing its top opening.

side with a relatively narrow longitudinally .extending opening/ladjacent its top edge and in addition has two air holes 5 on either sideof the lower'part ofits pointed or frontk end, whileV one ormoreopenings may be p rovided atitsv rear end to permit of its belngVconveniently lighted. The bottom or floor 6 of the body is, in thisinstance, made relatively thin and has fixed to it a comparatively thick`vertically perforated plate 7 of copper, 'although other metals of highheat conductivity ymay be employed if desired `without .departing frommy invention.

Mountedon the cover plate2V in any suitable manner is a handleconsisting of ay U-shaped piecel of relatively stiff metal strip 8 whoseupper ends "are connected `by a curvedf part 9 of wood or other poorconductor of heat, suchas fiber or vthe like.

8 by the screws 10.

Fixedto the cover plate 2 so as to extendf longitudinally within thehollow body of the iron is lan L-shaped burner tube 11 whoselonghorizontalarm has a number of openings 12'formed inits sidesandtunderr face.

through the second armof the handle 8 and' is connected'to one end of acontrolling valve structure 15` whose opposite end has. a"

gas jet nozzle 16 adjacent and in linewith the'` opening 'into the tubeor conduit `13. This nozzle lconsists of a conialy and rela.-

tively fixed needle valve 17,*concentric with which there is a series ofgas outlets 18 and "o'n it is vthreaded a cap 19.v Said cap has aycentral opening :which receives, and inv one position may be completelyclosed by, the valve structure 17, although ordinarily it would `besufficiently backed off to permit the gas flowing through the passages18'to-escape through said central. opening.

In the valve structure 15 1s mounted any suitable form of valve 20which, in the presmembers of the' part ent instance, is of the rotatabletype and has an operating arm 21 so acted on by a spring 22 as to benormally maintained in a par-- tially open position. Pivoted to the endof this arm'21 is a rod 23 which extends up'- y wardly through anopening in the rear part of the'handle bar 9 and thisrod carries on itsupper end a semi-annularor suitable form of head or hand piece 24:which, whenpies'itsfully open position.' vUnder` operating conditions,
